A few days back I bought a token from Launchpad. After they Launch on Pancakeswap I made 1.5X and sold. I was happy with that. But unfortunately, the token price grow double every day, then I bought again at the higher price. I thought this was a chance to multiply my portfolio again. Even though it grow 5x but O didn't sell that due to greedy behavior. Eventually, the project rug was pulled and skipped with all the funds. That means I lost everything even including my initial investment. This is how greed destroys us and scammer takes the advantage.
If only if you immediately exit the market when you have benefited from the initial investment even if only with a small amount then you don't have to feel it, but because we are human beings, we certainly can't always avoid greed and maybe almost all members in this forum too I've felt the same way you are feeling right now and I personally also experienced it when dealing with shitcoins last year.
